These symptoms are primarily related to malnutrition, particularly protein deficiency. The most common cause is chronic food allergies causing damage to the intestines. Any protein-containing food can potentially cause allergies. Infants are especially prone to food allergies due to immature protective functions of their gastrointestinal mucosa and incomplete immune systems.
Pay attention to the following four points to prevent food allergies:
(1) Extend breastfeeding duration to at least 6 months. During breastfeeding, mothers should avoid eating foods that can cause allergies.
(2) In the first year after the baby is born, focus on low-allergenic foods, and do not introduce solid foods too early.
(3) If any food is found to cause an allergic reaction, stop consuming it immediately. For foods that may cause allergies but the allergy might diminish with age, reintroduce them every six months, gradually increasing the amount to see if symptoms improve or disappear.
(4) Process foods deeply to remove, destroy, or reduce allergen content.
The second condition is myocardial injury, which leads to insufficient blood supply to the heart or rapid heart rate, causing increased consumption. Children with myocardial injury have noticeable characteristics:
1. Rapid heartbeat, easily excited, and influenced by the surrounding environment.
2. Excessive sweating, especially half an hour to two hours before sleep.
3. Prone to crying and irritability.
Such children have yellowish skin, and some may have yellow hands, feet, or palms. This condition can also be caused by consuming too many carotene-rich foods like carrots, pumpkins, and oranges.
